Hi Valerio,
It would be better to use a dictionary to store the names and then just change the data source of the editor. Here is an example for this:
Dictionary<string, string> displayNames;
protected override void OnLoad(EventArgs e)
{
base.OnLoad(e);
displayNames = new Dictionary<string, string>();
displayNames.Add("loc", "Location");
displayNames.Add("com", "Company");
foreach (var item in radGridView1.Columns)
{
if (displayNames.ContainsKey(item.FieldName))
{
item.HeaderText = displayNames[item.FieldName];
}
}
radDataFilter1.EditorInitialized += RadDataFilter1_EditorInitialized;
radDataFilter1.NodeFormatting += RadDataFilter1_NodeFormatting;
}
private void RadDataFilter1_NodeFormatting(object sender, TreeNodeFormattingEventArgs e)
{
DataFilterCriteriaElement dataExpressionFilterElement = e.NodeElement as DataFilterCriteriaElement;
if (dataExpressionFilterElement != null)
{
var node = dataExpressionFilterElement.Data as DataFilterCriteriaNode;
if (displayNames.ContainsKey(node.PropertyName))
{
dataExpressionFilterElement.FieldElement.Text = displayNames[node.PropertyName];
}
}
}
private void RadDataFilter1_EditorInitialized(object sender, Telerik.WinControls.UI.TreeNodeEditorInitializedEventArgs e)
{
var editor = e.Editor as TreeViewDropDownListEditor;
DataFilterCriteriaElement criteriaElement = e.NodeElement as DataFilterCriteriaElement;
if (editor != null && criteriaElement != null )
{
if (criteriaElement.EditingElement is DataFilterFieldEditorElement)
{
var element = editor.EditorElement as BaseDropDownListEditorElement;
element.DataSource = displayNames;
element.ValueMember = "Key";
element.DisplayMember = "Value";
}
}
}
Let me know if I can assist you further.
Regards,
Dimitar
